i’m not quite sure who this guy is. i think he digs the anonymity. part of the mystique. he’s got a lot more art and a web comic at the link above. however, this is one guy who you should ask permission first before posting his art. because he has a very particular set of skills; skills he has acquired over a long career. he will look for you. he will find you. and he will kill you.
actually he was pretty nice about it. and he created a tumblr specifically to address this issue, here.
